My gym has one of those 'things' with handles that meant to send 'waves' through you body to calculate the body fat.
So the trainer puts in my weight, weight, age & sex. I hold it out with my arms in line with my heart and then hold for a few seconds and it calculates the body fat.
The thing that calculates it is based on electrical resistance...something to do with muscles holding more water than fat, when combined with a weight measurement it yields an indication of body fat. I'd say it's more likely that the fluid/electrolyte balance in your body changed while you exercised (and drank water during exercise) and that would be reflected in a different reading.
Your trainer should understand that stuff otherwise it's a pretty meaningless kind of number to give you.
Yes you would think so wouldn't you Marydean?!! But he is a male trainer, so probably doesnt understand the very complicated female body! Especially mine as it seems to be very very strange at times...
So what would be more accurate - the reading before or after my sessions?
Aaahhh, so that explains it! I just had another check and we did it after i had already done a session at the gym and it was nothing like the first reading i had done! I decided to just ignore it and concentrate on other measures.
